Application Med January 10, 1921.

To all whom 'it may concern:

Be it known that I, Wai/ran P. MURPHY, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, have invented a new and useful Improvement in Car Roofs, of which the following is a specification. 4

This invention relates principally to heavy gage steel car roofs comprising roof sheets which s an the car from side to side and are rivete or otherwise secured together and to the car frame, and it relates more particularly to the manner of securing said roof to cars having wood side plates.

The principal objects of the present inveiiton are to obtain a waterproof eaves construction, to protect bolts which secure the roof to the substructure of the car, to stillen the eaves ends of the roof, to locate the securing rivets for the eaves ends of the sheet outside of the car, and to enable the roof to be assembled on a bench and applied to the car as a unitary structure. Other objects are simplicityhstrength, durability, and tightness. The invention conssts principally in means hereinafter set forth for securin heavy gage steel roofs to cars having woo construction, and in the combinations of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this specification, wherein like symbols refer to like parts wherever they occur,

Fig. 1 is a vertical cross-sectipn through the eaves ortion of a car roof embodying my invention and Fig. 2 is a similar section showing a modified form of eaves construction.

The present roof comprises rigid load sustaining roof sheets 5 of heavy gage steel, arranged crosswise of the car and preferably extending from eaves to eaves in arcs of circles. In Fig. 1, the side mar ins of adjacent sheets are lapped and rigi ly secured together by means of rivets 6. In Fig. 2, the side mar ns of adjacent sheets are turned up at rig t angles forming side flanges 7 which extend from end to end of the roof sheets. The side flanges are of the same height from the ridge to a point adjacent to the eaves where they mer into the plane of the body ofthe sheet. ressed sheet metal seam covers 8 of inverted U- lel'fll No. 486,170.

shape in cross-section embrace. the side flanges 7 of adjacent sheets, and the seam covers and flanges are fastened together by rivets 9. The seam covers are provided with lateral base flanges 10 and decrease gradually in hei ht from the ridge towards the eaves, at which point they merge into the plane of their base flanges. The eaves end of the seam covers are turned down, as at 13 over the depending flanges 12 of the roof sheets.

In the construction shown in Figs. 1 and 2 the eaves ends of the roof sheets overhang the side plate 11 of the car and are turned down, as at 12. The overhanging eaves ends of the roof sheets have one flange of an eaves angle strip 14 rigidly secured thereto by means of rivets 15. The eaves an le strips 14 extend lengthwise of the car an are disposed with their horizontal flanges upperinost and flush with the upper surface o the side plate and extending outwardly therefrom and with the other or vertical flanges secured to the outer side of the side plate, and in the construction shown in Fig. 2 the vertical flange of the angle strip is disposed in a longitudinal rabbet or recess 17 formed in the upper outer ed e of the side plate 11* and secured therein y means of a carriage bolt 16.

In the construction shown in 1 the upper edge of side sheathing boards 18 terminate below the lower edge of the eaves angle strip 14. In the construction shownl in Fig. 1, the vertical flange of the eaves angle strip is secured to the outer face of the side plate 11 by means of bolts 16. A wooden fascia 19 is secured to the side plate between the outer surfaceof said sheathing and the inner surface of the depending eaves flan e of the roof sheet by means of nails 20. The fascia 19 extends above the lower edge of the eaves flange of the sheet and below the top of the side sheathing, thereby covering the head of the securing bolt 16 and preventin rain or snow from entering the space ack of said fascia and thence reaching the interior of the car.

n the construction shown in Fi 2, the side sheathing 18* extends above t e lower edge of the eaves angle to within a short distance below the outwardly extending flange of said angle. A fascia 19* is disposed betweenthe sheathing 18l and the deending flange 12 of the roof sheets. The

p surface of the fascia bears against the under sido of the caves angle and said l'iisria is secured lo thi` side plate by nails 20 which are driven through the fascia and sheathing into the side plate. This ronsti'ui'tion also protects the bolt head and prevents water iiiid snow from reaching the interior of the cui'.

ln the constructions illustrated in the drawings, the fascia serves as a hatten for the up wi cnil of the sheathing and also protects tlie holt heads and acts as means for weiitlici'prooliiig llie joint between the side pluto und the side sheathing. lf desired, a drive lit may be obtained between the fascia and the depending eaves flan res of the sheets owing to the flexibility o said caves flanges.

One important advantage of the hereinbeforc described constructions is that the roof sheets can be assembled and riveted to tlii` connecting angle off the car before the same are applied to the car; that is, the whole roof may be assembled on the workslioi floor or other convenient location and app ied to the car as a unitary construction. \Vlien it is desired to iemove a damaged sheet, the fascia can be removed and the rivets securing said sheets to the eaves angle can be slieared, as the removal of the fascia allows ample room for cutting and redriving these rivets. If desired, the nuts can be placed on the outside of the side plate, thereby permitting the removal of the eaves angle from the outside of the car, although, in actual practice, it is referable to have the nuts on the inside fIdr the sake of inspection and to enable the nuts to be tightencd without removing the fascia.

What I claim is:

1. An eaves construction for car roofs comprisingr a side plate, metallic rooting extending outwardly beyond the outer face of said side plate, an angle having one flange secured to the outer face of said side late and having its other flange projecting t erefrom and secured to the under Side of said roofing, the eaves end of said roofing being turned down beyond the outer ed of the outwardly projecting flange of said angle side sheathing secured to the outer face o said side plate, and a fascia disposed between .iaid side sheathing and the downwardeaves end of said roofin and extendin above the lower edge of sai downturneil en( with its inner face flush with the outer face of said siding.

2. An eaves construction for car roofs com .rising a side plate, metallic roofing extent ing outwardly beyond the outer face of said side plate, an angle having one flange secured to the outer face of said side plato and having'its other flange projecting outi wardly therefrom and secured to the under side of said rooting, the eaves end of said roofing being turned down beyond the outer edge of the outwardly rojecting flange of said angle, side sheathing secured to the outer face of said side plate with the upper edge thereof terminating below said angle, and a fascia disposed between the downturned eaves end of said roolin and the side sheathing, said fascia exten ing abovc the lower edge of the downtiirned portion of said roofing and below the upper edge of said siding, with its inner surface flush with the outer surface of said side sheathin and with its outer surface in contact Wil i the turned down eaves portions of said roof sheets.

3. An eaves construction for car roofs comprising a side plate, side sheathing secured to the outer face of said side plate with the upper edge thereof disposed below the upper surface of the side plate, a fascia of substantiallyrectangular section secured to said sheathing and extending above the upper edge thereof and forming in connection therewith and with said side plate a vertical groove whose width corresponds lo the thickness of said sheathing, metallic roofing extending outwardly beyond the said side plate and having its eaves end turned downv over the outer edge of said fascia, and an angle bar disposed with one Harige in said groove and secured to said side plate and with the other flange up and extending outwardly and secured to the under side of said roofin 4.
